1. Escalation in the Israel-Iran Conflict

Timestamp: [00:02 - 06:05]

Overview: The episode opens with Ayesha Rascoe announcing Israel's warning of a prolonged conflict with Iran. Scott Simon delves into the sustainability of this conflict, questioning whether both nations possess the necessary weaponry for a long-term engagement.

Key Discussions:

• Israel's Air Defense Capabilities: Tom Carricko, Director of the Missile Defense Project at the Center for Strategic and International Studies, explains Israel's multilayered air defense system, highlighting the highly effective Iron Dome with a 90% success rate. However, he notes a significant challenge: "Iran has launched more than 400 missiles at Israel in recent days, along with hundreds of drones," [02:51], overwhelming Israel's interceptors.

• Potential Outcomes if Missile Interceptors Deplete: Carricko warns that if Israel exhausts its missile interceptors, "the longer this goes, Israel might have to start making some hard choices in terms of what to defend," [03:56]. This could lead to increased destruction of civilian infrastructure, potentially shifting the conflict's dynamics in Iran's favor.

• Iran's Missile Arsenal: The discussion moves to Iran's missile capabilities. While exact numbers are uncertain, experts estimate Iran has utilized about a third to half of its missile stockpile. Additionally, "Israel has taken out more than half of Iran's missile launchers," [05:20] crippling Iran's ability to deploy these weapons effectively.

• US Involvement Considerations: President Trump indicates a decision on potential US participation in the conflict within two weeks. Carricko emphasizes the humanitarian cost, stating, "Iran says 430 people have been killed. Israel says it's lost at least 24," [05:29].

Notable Quotes:

• Scott Simon: "President Trump says it's very hard to ask Israel to stop attacking Iran at this moment in the conflict. If somebody's winning, it's a little bit harder to do than if somebody's losing." [02:22]
• Tom Carricko: "The longer this goes, Israel might have to start making some hard choices in terms of what to defend." [03:56]

2. President Trump's Push for Tax Cuts and Spending Bill

Timestamp: [06:05 - 09:57]

Overview: Shifting focus to domestic politics, the episode covers President Trump's aggressive campaign to pass a substantial tax cut and spending bill. Senate Majority Leader John Thune is at the forefront of navigating internal Republican opposition to secure the bill's passage.

Key Discussions:

• Bill Overview and Differences from House Version: NPR Congressional Correspondent Rachel Martin outlines the Senate Republicans' version of the bill, emphasizing the permanent extension of 2017 tax cuts. Additional provisions include "no taxes on tips, no taxes on overtime," and significant "cuts to Medicaid," [06:44]. The bill also aims to phase out "hundreds of billions of dollars in clean tax breaks" introduced by the Biden administration.

• Division Within Senate Republicans: Martin highlights several points of contention among Republicans:

  • Rand Paul's Opposition: He rejects the "$5 trillion increase in the country's borrowing authority," [07:31].
  • Spending Cuts Insufficiency: Some conservatives argue the bill doesn't reduce spending enough.
  • Medicaid Changes: Concerns that alterations could harm rural hospitals.
  • Energy Tax Breaks: Representatives from energy project states seek delays in phasing out these incentives.

• Negotiation Efforts: Senate Majority Leader Thune is attempting to mediate these divisions with the assistance of President Trump's Chief of Staff, Susie Wiles. Despite efforts, there's skepticism about meeting the July 4th deadline, especially with impending debt ceiling pressures.

• Congressional Resolution on Iran: In parallel, Senator Tim Kaine introduces a resolution requiring presidential consultation with Congress before any military action against Iran. While Kaine anticipates bipartisan support, no Republicans have committed to voting in favor as of the discussion.

Notable Quotes:

• Senator Thune: "If we don't take action, American families will be facing a massive tax hike starting in 2026." [06:21]
• Rachel Martin: "This bill makes significant cuts to Medicaid... and it adds new work requirements." [06:44]

3. Looming Heat Dome Threatening the U.S.

Timestamp: [09:57 - 13:45]

Overview: Ayesha Rascoe and Scott Simon shift to environmental news, discussing an impending heat dome set to engulf much of the United States. Meteorologist Ben Knoll from the Washington Post provides expert analysis on the phenomenon's causes and associated risks.

Key Discussions:

• Heat Dome Characteristics and Impact: Ben Knoll describes the heat dome as "really brutally humid" [10:35], affecting approximately 265 million people across the U.S., with temperatures soaring into the 90s and triple digits.

• Causes Behind the Extreme Weather: The heat dome results from "winds blowing up from the Caribbean Sea," transporting warm, moisture-laden air into the U.S. Additionally, "the ocean waters in those parts of the world are warmer than average," allowing the atmosphere to hold more water vapor, thereby increasing humidity levels [11:05].

• Climate Change Connection: Knoll asserts that the high humidity levels are "part of that bigger picture" of climate change, noting that 2024 was the most humid year on record [11:54]. Warmer temperatures correlate with increased water vapor capacity in the atmosphere, leading to consistent trends of higher humidity.

• Health Risks Associated with High Humidity: Elevated humidity hampers the body's ability to cool down through sweating, elevating the risk of heat-related illnesses such as heat stroke and heat stress [12:37]. Knoll advises staying in air-conditioned environments, using dehumidifiers, taking cool showers, and staying hydrated to mitigate these dangers.

Notable Quotes:

• Ben Knoll: "A warmer world actually is often a wetter world." [12:33]
• Ben Knoll: "High humidity... makes it more challenging to cool off." [12:37]

[Ayesha Rascoe]

Israel warns of a prolonged conflict with Iran.

[Scott Simon]

But with the war now in its second week, do the two countries have the weapons to fight a sustained campaign? I'm Scott Simon.

[Ayesha Rascoe]

I'm Ayesha Rascoe. And this is up first from NPR News.

[Scott Simon]

President Trump is pushing to pass his massive tax cut and spending bill by as early as next week, but he'll.

[Ayesha Rascoe]

Need to overcome opposition from within his own political ranks. Can the president close the deal?

[Scott Simon]

And we're about to have the first heat wave of the summer.

[Ayesha Rascoe]

Record breaking temperatures are expected to affect millions of Americans, and extreme humidity is also a big concern. Stay with us. We have the news you need to start your weekend.

[Scott Simon]

President Trump says it's very hard to ask Israel to stop attacking Iran at this moment in the conflict. If somebody's winning, it's a little bit harder to do than if somebody's losing.

[Ayesha Rascoe]

But there's a specific kind of math that could determine just how long the.

[Scott Simon]

War could go on for how many long range missiles Iran has versus how many missile interceptors Israel possesses to shoot them down. NPR's Kat Lansdorf has been looking into this issue and joins us. Kat, thanks for being with us.

[Tom Carricko]

Hey, good morning.

[Scott Simon]

Help us get hold of this. Describe first Israel's air defense system.

[Tom Carricko]

Yeah. So Israel has one of the best, if not the best, air defense systems in the world, and it's multilayered. Probably the most well known layer of that is called the Iron Dome. But there are several others at work, too, and the system works well. It generally has about a 90% success rate. What makes this situation different is essentially sheer numbers. Iran has launched more than 400 missiles at Israel in recent days, along with hundreds of drones, according to Israel. And Iran continues to barrage Israel daily, often usually with dozens of missiles at a time. That means, basically, Israel is using its missile interceptors faster than it can make them right now. Here's Tom Carricko. Here's how he put it to me. He's the director of the Missile Defense Project at the center for Strategic and International Studies.

[Scott Simon]

Whenever you're talking about somebody shooting big ballistic missiles at you, you pay real close attention to the clock in terms.

[Ben Knoll]

Of how long you can shoot back, you know.

[Tom Carricko]

He says his biggest worry right now is that eventually Israel's missile interceptors could run out.

[Scott Simon]

And what would that mean for Israel?

[Tom Carricko]

Well, the longer this goes, Israel might have to start making some hard choices in terms of what to defend, maybe focusing on key military or security targets versus civilian infrastructure, for example, meaning that Israeli cities and towns might start seeing more destruction. Experts I talked to say this would be a big win for Iran, hoping it might put more pressure on Israel to give up on its goal of destroying Iran's nuclear infrastructure. I should say Israeli officials won't comment on how many interceptors it has left. That would potentially give Iran a big advantage. NPR asked the Israeli military about its stock of interceptors and it said it is, quote, prepared and ready for any scenario.

[Scott Simon]

And what about the other side of the equation? What do we know about the Iranian arsenal?

[Tom Carricko]

Yeah, that's the other key piece of this, of course, is how many long range missiles Iran has to shoot and what it has to shoot them with. There aren't many reliable estimates on Iran's stockpile, but experts tend to think that Iran has used around a third to a half of what it has. But perhaps more important is how many missile launchers Iran has because it can't use the missiles without them. Launchers have been a key target for Israeli strikes. Israeli Prime Minister Benjamin Netanyahu estimated earlier this week that Israel has taken out more than half of them, although that number is hard to know for sure. And another upper hand for Israel is that it's crippled Iran's air defense systems, claiming it has total control over the skies there and it can hit whatever it wants at will.

[Scott Simon]

And President Trump says he would decide within two weeks if the US Would join Israel's bombing campaign against Iran. What would be at stake?

[Tom Carricko]

Well, we know the White House has been weighing whether or not to greenlight using these huge bunker buster bombs that only the US has to try to destroy a key Iranian nuclear site. Obviously, Israel having control of Iran's airspace would be a huge help for that. But Scott, maybe the most important numbers and all of this to keep in mind here are the civilian lives being lost on both sides if this war continues. Iran says 430 people have been killed. Israel says it's lost at least 24.

[Scott Simon]

NPR's Kat Lansdorf, thanks so much.

[Tom Carricko]

Thanks, Scott.

[Scott Simon]

This week's news, of course, has been dominated by events in the Middle East. But at home, President Trump is pressing ahead with his domestic agenda.

[Ayesha Rascoe]

Senate Majority Leader John Thune warned what's at stake if Congress doesn't pass the president's massive tax cut and spending bill.

[Hari Sreenivasan]

If we don't take action, American families will be facing a massive tax hike starting in 2026.

[Scott Simon]

Senator Thune aims for a vote next week, but first he has to resolve divisions among his own fellow Republicans. NPR congressional correspondent Deidre Walsh joins us. Deirdre, thanks for being with us.

[Rachel Martin]

Thanks, Scott.

[Scott Simon]

Remind us, please, first, how is this bill significantly different than the one the House passed last month?

[Rachel Martin]

Senate Republicans did make some changes to the version that cleared the House last month. But the core elements of this bill are the bill permanently extends the tax cuts for individuals and businesses that Trump enacted back in 2017. But Republicans added some additional ones, things the president campaigned on, like no taxes on tips, no taxes on overtime to pay for the tax cuts. This bill makes significant cuts to Medicaid. That's the health care program for low income elderly and disabled Americans. It adds new work requirements and changes the way states can finance their Medicaid programs. This bill also phases out hundreds of billions of dollars in clean tax breaks that the Biden administration put into place.

[Scott Simon]

And Senate Republicans are split on this package. Right. Where are some of the divisions?

[Rachel Martin]

Right. There are several issues. Rand Paul of Kentucky, for one, says the provision to increase the country's borrowing authority by $5 trillion to avoid a default later this summer is a non starter for him. Some conservatives say the bill doesn't cut enough spending. Another group of Republicans in the Senate oppose the Medicaid changes. They're worried that some of the changes could cause rural hospitals in their states to there's another group of Senate Republicans who represent states where new energy projects are getting up and running and generating jobs. And they want to delay phasing out those energy tax breaks so these projects can move ahead. Remember, Senate Majority Leader Thune can afford to lose only three votes to get this package through.

[Scott Simon]

And what's the senator doing to try and bridge some of the differences?

[Rachel Martin]

He's relying heavily on President Trump to be the closer. White House Chief of Staff Susie Wiles was on the Hill meeting with Senate Republicans this week, and she reiterated the president wants this done by July 4th. There are discussions making tweaks to some of the things that I just talked about to address these concerns. But for people like John Thune, it's kind of like whack a mole. If you give in to moderates on Medicaid, it could impact how conservatives view the bill in terms of its spending cuts. And whatever changes Senate Republicans make, we'll need to get a majority in the House. And there's already a group of House Republicans who are raising red flags about some of these changes that the Senate's making. It's pretty clear this could slip beyond July 4th. That's not a real hard deadline. The real deadline comes later this summer when the Treasury Department warns the country could bump up against the debt ceiling if Congress doesn't authorize more borrowing.

[Scott Simon]

Separately, the Senate next week is expected to take up a resolution related to Iran. Right?

[Rachel Martin]

Right. As the president weighs whether or not to take military action against Iranian nuclear facilities, Virginia Democratic Senator Tim Kaine is forcing a vote on a resolution. That resolution says the president cannot military action against Iran without first coming to Congress for a vote. Kaine says he does expect some Republicans to join him, but so far, no Republican has said they're voting for this resolution. There will be intelligence briefings on the Hill early next week on Iran, and that could really impact the vote on this kind of resolution.

[Scott Simon]

NPR's Deidre Walsh, thanks so much.

[Rachel Martin]

Thank you.

[Ayesha Rascoe]

For much of the country, summer is about to be off to a blistering start.

[Scott Simon]

A heat dome is expanding over much of the US it's expected to raise temperatures well into the 90s, even into triple digits in the coming days.

[Ayesha Rascoe]

And along with this extreme heat is unusually high humidity, which presents its own set of dangers. Ben Knoll is a meteorologist with the Washington Post, and he joins us now. Hi, Ben.

[Ben Knoll]

Good morning.

[Ayesha Rascoe]

So how hot and humid is it going to get in the US because here in DC it is hot as Hades. Can I say that?

[Ben Knoll]

Yeah. Look, I've just run some of the latest statistics, and we're looking at about 265 million people across the country experiencing 90 or 100 degree heat over the next week. And this is interesting because I think this event can kind of interchangeably be called a heat wave or a humidity wave because it's going to be really brutally humid across the central and eastern part of the country.

[Ayesha Rascoe]

What is causing that? Why is there so much moisture in the air?

[Ben Knoll]

So the winds in this case are blowing up from the Caribbean Sea, so thousands of miles away, transporting kind of the weather from the Caribbean islands, from the Gulf of Mexico right up into the United States. But it's not just that. Actually the ocean waters in those parts of the world are warmer than average. And warmer air, air can hold more water vapor. And that's what millions of people across the United States are going to feel. Places like Minneapolis, Chicago, New York, Washington, Baltimore, down into the Carolinas, even up into southern Canada, places that you wouldn't normally, I guess, associate with extreme humidity. Feeling honestly more like the tropics for a couple of days next week.

[Ayesha Rascoe]

This high humidity, is that a part of climate change?

[Ben Knoll]

I think it is. It is part of that bigger picture. I mean, summer, it's hot, it's humid. But you can look back historically at humidity over the course of many past summers and look at how that is changing and what you find is a gradual trend toward more humidity. For the planet as a whole, the year 2024 last year was the most humid by one particular metric of humidity measuring on record since records began in 1940. So this is a real trend and it's kind of linked the fact that a warmer atmosphere can basically contain, you know, more water vapor. So a warmer world actually is often a wetter world.

[Ayesha Rascoe]

What are the specific dangers associated with high humidity?

[Ben Knoll]

It makes the human body, makes it more challenging to cool off. The human body cools off by sweating that sweat, which needs to evaporate off of the skin. It can't evaporate as quickly or as efficiently in an atmosphere that is very humid. So that sweat kind of lingers, it sticks around your body temperature starts to go up. And that's when kind of heat related illnesses, heat stroke, heat stress can come into the picture. So remaining kind of in an air conditioned place, if you have access to that, some folks may have a dehumidifier that can help. If you don't have those two things, cool showers, if you have to work outside, you know, listen to your body, take breaks, drink water preferably, and not, you know, other beverages that can actually dehydrate you. So it's kind of, you know, knowing your limits because they can kind of creep up on you fast in weather like this.

[Ayesha Rascoe]

That's Ben Knoll, a meteorologist with the Washington Post. Thank you so much for joining us.

[Ben Knoll]

Yeah, thanks so much for having me.
